Title: Swirl-chamber type diesel engine
Inventor: MIYAJIMA KEITAROU
IPC: F02B19/08
Filed: 1981-02-09
Abstract: PURPOSE:To improve combustion efficiency under a light load and at a low  speed zone and starting performance during cold starting by inserting a heat  pipe in a fuel injection path where a fuel injection nozzle is installed. CONSTITUTION:A heat pipe 10 is inserted so that its aperture faces the inside of a minor combustion chamber 1 and a ring-shaped gap 11 is provided toward the interior of a fuel injection path 9. Holes 13 are bored at optimum places on the circumference of the heat pipe 10, and a glow plug 8 is projected near the aperture of the heat pipe 10 in the minor combustion chamber 1. Accordingly, less fuel clings to the inner wall of the minor combustion chamber 1, mixing of injected fuel with air is enhanced because of heating, thus ignition efficiency and combustion efficiency are improved. Since the injected fuel is heated without fail by getting in touch with the glow plug 8, starting performance of the  engine during cold starting is also improved.

Title: Method for controlling injection of chlorine in water purifying plant
Inventor: KOBAYASHI TOSHIAKI
IPC: C02F1/50
Filed: 1982-02-08
Abstract: PURPOSE:To control the injection amount of chlorine for holding the concentration of chlorine remaining in purified water at a predetermined value, by combining a mechanism for feeding back the concentration of chlorine remaining in purified water by PID calculation with a mechanism for automatically calculating the consumption ratio of chlorine. CONSTITUTION:The injection ratio of chlorine (MVB) by feed-back is obtained by a PID arithmetic unit 15. The actually measured value (PV) of the concentration of residual chlorine, a preset value (SV) and the idling time of a process corresponding to the flow amount of intake water obtained by an arithmetic unit 17 are inputted to the arithmetic unit 15. The injection ratio of chlorine (MVB) obtained by feed-back control is added together with a reference injection ratio (MVS) by an arithmetic unit 18 to determine the injection ratio (MV) of chlorine. Said injection ratio of chlorine is converted into the injection amount of chlorine corresponding to the flow amount of intake water by an arithmetic unit 11 for calculating a ratio and utilized for controlling the opening ratio of the valve of a chlorine injector 8 or the like. In this way, the proper injection amount of chlorine can be maintained.

Title: Magnetic head
Inventor: FUKUHARA YOSHIKAZU
IPC: G11B5/17
Filed: 1985-02-05
Abstract: PURPOSE:To omit a core support by deforming some part of a coil bobbin assembly and extending slightly the side edge of a reinforcing plate for holding a core half body. CONSTITUTION:Side edges of the reinforcing plates 3 and 3', which support one core half body 2 by holding it vertically, are extended by an appropriate dimension L1 to provide an extended part 3b. One flange of the bobbin assembly 6 has a section which can hold one of the core half body 2 in a U-shaped frame 6a. The core half body 2 in such a structure and the bobbin assembly 6 are used instead of the conventional core support to assemble a magnetic head base 8. Codes L4 and L5 denote the width of the core half body where the reinforcing plate with the extended part 3b is fixed and the overall width of the bobbin assembly 6, respectively. If the sum of the L4 and L5 is set slightly larger than an L3 in terms of dimensions, the entire magnetic head base 8 is pressed to the right and left inner surfaces of a shield case 1 due to the elastic force of the frame 6a of the bobbin assembly 6 made of 'Duracon(R)' and other synthetic resins, and is securely fixed.

Title: Predrive circuit
Inventor: NAKAMURA SHIGEO
IPC: H03K17/695
Filed: 1987-01-29
Abstract: PURPOSE:To simplify the constitution of a control circuit and to prevent unnecessary heat generation by providing a feedback circuit which connects the control terminal of the second switching element and the signal output terminal of a first switching element. CONSTITUTION:Since the output is fed back from the collector of a switching element Q2 to the gate of a switching element Q3 by the feedback circuit, the switching element Q3 is not turned on unless the electric charge of the base of the switching element Q2 is completely extinguished and the collector voltage rises to several volt in case of switching of a transistor TR switching element Q1 from the turning-on state to the turning-off state. Consequently, a TR Q4 for signal output of the control circuit is turned on to simultaneously turn on and off switching elements Q2 and Q3 respectively. When the power TR Q1 is turned on and the TR Q4 is turned off, the switching element Q3 is not turned on till the switching element Q2 is turned off. Thus, an excessive current due to simultaneous turning-on of switching elements Q2 and Q3 does not occur in a predrive circuit to prevent heat generation.

     CONSTITUTION: When an amount of air 5 to be fed into crude water 6 in an aeration vessel 1 through a sparger 4 from a blower 3 is about two times or more of a proper air amount, active sludge 7 which has formed mold fungus-type or non mold fungus-type bulking can not be recovered or reformed within a short period. On the other hand, about two times or more of the air amount, practically 30Nm 3 /m 2 .day of an air amount (6Nm 3 /m 2 .day expressed in terms of oxygen), is fed, an indication SV 1  representing the precipitating property of the active sludge is gradually lowered by continuing said air feed for 4W20days depending on the bulking state. Thus, the bulking sludge is reformed.
